江苏北部山丘区植被内部差异研究

STUDY ON THE DIFFERENCE OF VEGETATION IN THE NORTHERN HILL AREA OF JIANGSU

从植物区系及植物群落上比较研究苏北山丘区植被内部差异，并从气候、岩性、土壤等差异上探讨植被内部差异形成的原因．研究表明，苏北山丘区植被植物区系差异不明显，但在东西方向上植物群系有明显差异，岩性、土壤是造成这种差异的主导因素，但气候因素也起一定作用．

The vegetational difference is studied by comparing the flora and phytocoenose.The conclusions achieved are as follows:(1)the difference of flora in this area is not obvious;(2)the difference of phytocoense fromeast to west are obvious;(3)the main factors resulting in those differences are the difference of lithology and soil,the secondary factor is climate.
